TECHNICAL FIELD

The present disclosure is related to video games. Among other things, this disclosure describes methods and systems for saving snapshots generated at various points during game plays by multiple users of a video game, wherein the snapshots can be used by one user to jump into a previously saved game play of another user, particularly when executing the video game on a cloud-based gaming system.

BACKGROUND OF THE DISCLOSURE

Cloud-based systems, using computing resources (hardware and software), deliver services over a network (e.g., the internet). The services, in the context of gaming, enable streaming of content to remote clients, wherein most processing is done on servers, which may be distributed. Input provided at the remote clients will in turn drive execution of the video game, without the need for dedicated gaming hardware at the client's location. Cloud-based gaming, therefore, has been increasing in popularity because users find it easier to access more video game titles without complex hardware restrictions, and game suppliers find it easier to manage game code from centralized locations.

As a user is progressing through a game play of a video game that may present multiple options giving different results, it may be difficult to decide in which direction to steer the game play. For example, though a user may want to avoid directions that do not provide any appreciable advancement in the game play, without prior knowledge gained through outside sources the user cannot avoid a particular direction that results in a dead-end. In some cases, the user may exhaust all possible directions that a video game may present in a certain portion of the game before discovering the proper direction that gives a result advancing the game play. It may be desirable to avoid playing all possible directions in a video game.

It is in this context that embodiments of the disclosure arise.

DETAILED DESCRIPTION

Although the following detailed description contains many specific details for the purposes of illustration, anyone of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the present disclosure. Accordingly, the aspects of the present disclosure described below are set forth without any loss of generality to, and without imposing limitations upon, the claims that follow this description.

Generally speaking, the various embodiments of the present disclosure describe systems and methods providing for the saving of snapshots that are generated during game plays of a video game of multiple users, navigating through a video game, previewing a video game, and jumping to a selected point in the video game to experience the game play of another user, particularly when executed on a cloud-based gaming system. The snapshots may be displayed in a timeline for a user playing the video game. A selected snapshot in the timeline contains metadata and/or information enabling the instantiation of an instance of the video game at a jump point in the video game corresponding to the selected snapshot. The instance of the video game beginning at the jump point is executed in association with an original user generating the selected snapshot in a previously executed game play, even though the requesting user may be different than the original user. Embodiments of the present disclosure provide for a way to load and execute an instance of a video game of the same or another user that previously was unavailable. In that manner, the user is able to actively preview game plays of other users without jeopardizing his or her own game play. Also, the user is able to actively preview his or her own previous game play without jeopardizing his or her own current game play. It is in this context that embodiments of the disclosure arise.

Accordingly, embodiments of the present disclosure provide for additional uses of a gaming application. For example, embodiments of the present disclosure provide for a user to jump into any part of a gaming application based on previous game plays of that gaming application. For example in some embodiments, through selection of a snapshot image (e.g., screenshot), corresponding snapshot information is accessed to enable the jump into that gaming application. In that manner, the user is able to quickly play mini-sections of the gaming application for enjoyment, or to discover how to successfully navigate through difficult sections of the gaming application. Access to the mini-sections is accomplished without the user having to load the gaming application using an initial start-up sequence. Furthermore, older applications that have fallen out of favor will generate new interest, as the user need not play the entire game to get to the interesting sections (e.g., battling level bosses, or the ultimate boss), but can go directly to those interesting sections for immediate game play. Still other embodiments provide the above accomplishments, and provide additional benefits and advantages including better utilization of game servers, since instead of executing an initialization sequence from the beginning (e.g., when the user first loads a gaming application from scratch), the game server need only execute the gaming application beginning directly from a mid-point or jump-point. As such, by directly uploading the code necessary to begin the game from the selected jump point, the game server skips the initialization sequence, and also any further executable sequence to navigate to the jump point in the gaming application.

With the above general understanding of the various embodiments, example details of the embodiments will now be described with reference to the various drawings.

Throughout the specification, the reference to “video game” is meant to represent any type of interactive application that is directed through execution of input commands. For illustration purposes only, an interactive application includes applications for gaming, word processing, video processing, video game processing, etc. Further, the terms video game and gaming application are interchangeable.

FIG. 1 illustrates a system used for saving of snapshots generated during game plays of a video game of multiple users executed over a cloud game network, previewing game plays of a video game of one or more users, navigating through a video game, and jumping to a selected point in the video game to experience the game play of the same or another user, in accordance with one embodiment of the present disclosure.

In some embodiments, the cloud game network may include a plurality of virtual machines (VMs) running on a hypervisor of a host machine, with one or more virtual machines configured to execute a game processor module utilizing the hardware resources available to the hypervisor of the host in support of single player or multi-player video games. In other embodiments, the cloud game network is configured to support a plurality of local computing devices supporting a plurality of users, wherein each local computing device may be executing an instance of a video game, such as in a single-player or multi-player video game. For example, in the multi-player mode, while the video game is executing locally, the cloud game network concurrently receives information (e.g., game state data) from each local computing device and distributes that information accordingly throughout one or more of the local computing devices so that each user is able to interact with other users (e.g., through corresponding characters in the video game) in the gaming environment of the multi-player video game. In that manner, the cloud game network coordinates and combines the game plays for each of the users within the multi-player gaming environment.

As shown, system 10 includes a game server 205 executing the game processor module 210 that provides access to a plurality of interactive video games. Game server 205 may be any type of server computing device available in the cloud, and may be configured as one or more virtual machines executing on one or more hosts. For example, game server 205 may manage a virtual machine supporting the game processor 210.

Client device 100 is configured for requesting access to video games over a network 150, such as the internet, and for rendering instances of video games executed by the game server 205 and delivered to the display device 12 associated with a user 5. For example, user 5 may be interacting through client device 100 with an instance of a video game executing on game processor 210. Client device 100 may also include a game executing engine 111 configured for local execution of a video game. The client device 100 may receive input from various types of input devices, such as game controllers 6, tablet computers 11, keyboards, gestures captured by video cameras, mice, touch pads, etc. Client device 100 can be any type of computing device having at least a memory and a processor module that is capable of connecting to the game server 205 over network 150. Some examples of client device 100 include a personal computer (PC), a game console, a home theater device, a general purpose computer, mobile computing device, a tablet, a phone, or any other types of computing devices that can interact with the game server 205 to execute an instance of a video game.

Client device 100 is configured for receiving rendered images delivered by the game server 205 or locally by the game executing engine 111, and for displaying the rendered images on display 12. For example, the rendered images may be associated with an instance of a video game executing on game executing engine 211 of game server 205 in association with user 5. In particular, client device 100 is configured to interact with the instance of the video game associated with game play of user 5, such as through input commands that are used to drive game play.

Further, client device 100 is configured to interact with the game server 205 to capture and store snapshots of the game play of user 5 when playing a video game. In addition, client device 100 is configured to interact with game server 205 to display a timeline including snapshots of the game play of user 5, as well as snapshots of saved game plays of other users playing the same video game. Each snapshot enables user 5 to jump into a saved game play at a jump point in the video game corresponding to the selected snapshot, wherein the saved game play may be associated with another user different than user 5, in one embodiment.

More particularly, game processor 210 of game server 205 is configured to generate snapshots of the game play of user 5 when playing the video game. Other game processors of game server 205 associated with other virtual machines are configured to execute instances of the video game associated with game plays of other users and to capture snapshots during those game plays. As previously introduced, an instance of the video game is executing on the game executing engine 211 in association with game play of the user 5.

Snapshot generator 212 is configured to capture a plurality of snapshots generated from the game play of user 5. Each snapshot provides information that enables execution of an instance of the video game beginning from a point in the video game associated with a corresponding snapshot. The snapshots are automatically generated during game play of the video game by user 5. Portions of each of the snapshots are stored in relevant databases independently configured or configured under data store 140, in embodiments. In another embodiment, snapshots may be generated manually through instruction by user 5. In that manner, any user through selection of a corresponding snapshot may jump into the game play of user 5 at a point in the video game associated with the corresponding snapshot. Game processor 210 is configured to access information in database 140 in order to enable the jumping into a saved game play of any user based on a corresponding snapshot. That is, the requesting user is able to begin playing the video game at a jump point corresponding to a selected snapshot using the game characters of the original user's game play that generated and saved the snapshot.

In particular, each snapshot includes metadata and/or information to enable execution of an instance of the video game beginning at a point in the video game corresponding to the snapshot. For example, in the game play of user 5, a snapshot may be generated at a particular point in the progression of the video game, such as in the middle of a level. The relevant snapshot information is stored in one or more databases of database 140. Pointers can be used to relate information in each database corresponding to a particular snapshot. In that manner, another user wishing to experience the game play of user 5 may select a snapshot corresponding to a point in the video game of interest.

The snapshot includes a snapshot image of the scene that is rendered at that point. The snapshot image is stored in snapshot image database 146. The snapshot image presented in the form of a thumbnail in a timeline provides a view into the game play of a user at a corresponding point in the progression by the user through a video game.

The snapshot also includes game state data that defines the state of the game at that point. For example, game state data may include game characters, game objects, game object attributes, game attributes, game object state, graphic overlays, etc. In that manner, game state data allows for the generation of the gaming environment that existed at the corresponding point in the video game. Game state data may also include the state of every device used for rendering the game play, such as states of CPU, GPU, memory, register values, program counter value, programmable DMA state, buffered data for the DMA, audio chip state, CD-ROM state, etc. Game state data may also identify which parts of the executable code need to be loaded to execute the video game from that point. Not all the game state data need be captured and stored, just the data that is sufficient for the executable code to start the game at the point corresponding to the snapshot. The game state data is stored in game state database 145.

The snapshot also includes user saved data. Generally, user saved data includes information that personalizes the video game for the corresponding user. This includes information associated with the user's character, so that the video game is rendered with a character that may be unique to that user (e.g., shape, look, clothing, weaponry, etc.). In that manner, the user saved data enables generation of a character for the game play of a corresponding user, wherein the character has a state that corresponds to the point in the video game associated with the snapshot. For example, user saved data may include the game difficulty selected by the user 5 when playing the game, game level, character attributes, character location, number of lives left, the total possible number of lives available, armor, trophy, time counter values, etc. User saved data may also include user profile data that identifies user 5, for example. User saved data is stored in database 141.

In addition, the snapshot also includes random seed data that is generated by artificial intelligence (AI) module 215. The random seed data may not be part of the original game code, but may be added in an overlay to make the gaming environment seem more realistic and/or engaging to the user. That is, random seed data provides additional features for the gaming environment that exists at the corresponding point in the game play of the user. For example, AI characters may be randomly generated and provided in the overlay. The AI characters are not associated with any users playing the game, but are placed into the gaming environment to enhance the user's experience. As an illustration, these AI characters may randomly walk the streets in a city scene. In addition, other objects maybe generated and presented in an overlay. For instance, clouds in the background and birds flying through space may be generated and presented in an overlay. The random seed data is stored in random seed database 143.

In that manner, another user wishing to experience the game play of user 5 may select a snapshot corresponding to a point in the video game of interest. For example, selection of a snapshot image presented in a timeline or node in a node graph by a user enables the jump executing engine 216 of game processor 210 to access the corresponding snapshot, instantiate another instance of the video game based on the snapshot, and execute the video game beginning at a point in the video game corresponding to the snapshot. In that manner, the snapshot enables the requesting user to jump into the game play of user 5 at the point corresponding to the snapshot.

Game processor 210 includes a timeline generator 213 that is displaying a timeline of user 5 playing the video game. The timeline includes snapshot images of at least one user (e.g., user 5 and/or other users) progressing through the video game, wherein the snapshot images are presented in relation to a currently rendered image of the instance of the video game executing in association with user 5. Each snapshot image corresponds to a particular snapshot that is captured at a particular point in the progression of the video game by user 5. For example, snapshots and snapshot images generated in association with the game play of user 5 correspond to points in the video game occurring before a currently rendered image of an instance of the video game executing in association with the game play of user 5. That is, user 5 previously played through those points in the video game, and multiple snapshots and snapshot images were generated corresponding to those points.

In addition, snapshots and their corresponding snapshot images generated in association with the game play of a second user may correspond to points in the video game occurring before or after a currently rendered image of the game play of user 5. That is, the second user may have progressed further than user 5 when playing the video game. As such, snapshots corresponding to the game play of the second user may occur at points in the video game before the currently rendered image associated with the game play of user 5, or may occur at points after the currently rendered image. The timeline may include snapshot images corresponding to points in the video game occurring after the currently rendered image, and/or may include snapshot images corresponding to points in the video game occurring before the currently rendered image.

Snapshots presented in the timeline may be used to access game plays of other users by user 5, in one embodiment. That is, selection of a selected snapshot in the timeline enables user 5 to jump into the game play of another user at the point corresponding to the snapshot. For example, the jump game executing engine 216 collects the snapshot (e.g., metadata and/or information) from the various databases (e.g., from database 140) in order to the begin executing the video game at the point corresponding to the selected snapshot. In one embodiment, the game play of user 5 is unaffected by jumping to the game play of another user.

In another embodiment, snapshots presented in the timeline may be used by user 5 to access a point in the user's own game play that occurs before the currently rendered image. For example, a snapshot may be generated in the game play of user 5, and presented in the timeline. Selection of the snapshot by user 5 enables executing engine 216 to collect the snapshot (e.g., metadata and/or information) from the various databases (e.g., from database 140) in order to begin executing the video game at the previous point corresponding to the selected snapshot. In that manner, user 5 may go back and replay certain portions of the video (e.g., a previous level). In one embodiment, the current game play of user 5 is unaffected by jumping to a previous game play of the same user.

Game processor 210 also includes a node graph generator 214. As user 5 progresses through the video game, a path through the game is generated. Another user may generate a different path through the video game, especially if the video game is complex. The path may be part of the universal logical path established by the video game, wherein the universal logical path includes all paths that any user may take when playing the video game. As such, the path associated with the game play of user 5 may be a subset of the universal logical path, and defines the progress of user 5 through the video game. Logical nodes may be defined at various points in the universal logical path. For instance, by way of illustration nodes may be established at the start of game, start of level, end of game, end of level, forks allowing the user to select between two or more optional paths, critical points in the video game, etc.

In addition, nodes may be defined at various points in the path associated with the game play of user 5, or more generally in a path associated with the game play of any user. For example, nodes may be defined in association with a snapshot. These nodes may be defined at periodic intervals (e.g., every minute, 5 minutes, 10 minutes, etc.). In addition, these nodes may be manually defined by the user. For illustration, these nodes may also be established at the start of game, start of level, end of game, end of level, forks allowing the user to select between two or more optional paths, critical points in the video game, etc.

FIG. 2 illustrates a system diagram 200 for enabling access and playing of video games stored in a game cloud system (GCS) 201, in accordance with an embodiment of the disclosure. Generally speaking, game cloud system GCS 201 may be a cloud computing system operating over a network 220 to support a plurality of users. Additionally, GCS 201 is configured to save snapshots generated during game plays of a video game of multiple users, wherein a snapshot can be used to initiate an instance of the video game for a requesting user beginning at a point in the video game corresponding to the snapshot. In addition, GCS 201 through the use of snapshots enables a user to navigate through a video game, and preview past and future scenes of a video game. Further, the snapshots enable a requesting user to jump to a selected point in the video game through a corresponding snapshot to experience the game play of another user. In particular, system 200 includes GCS 201, one or more social media providers 240, and a user device 230, all of which are connected via a network 220 (e.g., interna). One or more user devices may be connected to network 220 to access services provided by GCS 201 and social media providers 240.

In one embodiment, game cloud system 201 includes a game server 205, a video recorder 271, a tag processor 273, and account manager 274 that includes a user profile manager, a game selection engine 275, a game session manager 285, user access logic 280, a network interface 290, and a social media manager 295. GCS 201 may further include a plurality of gaming storage systems, such as a game state store, random seed store, user saved data store, snapshot store, which may be stored generally in datastore 140. Other gaming storage systems may include a game code store 261, a recorded game store 262, a tag data store 263, video game data store 264, and a game network user store 265. In one embodiment, GCS 201 is a system that can provide gaming applications, services, gaming related digital content, and interconnectivity among systems, applications, users, and social networks. GCS 201 may communicate with user device 230 and social media providers 240 through social media manager 295 via network interface 290. Social media manager 295 may be configured to relate one or more friends. In one embodiment, each social media provider 240 includes at least one social graph 245 that shows user social network connections.

User U₀ is able to access services provided by GCS 201 via the game session manager 285, wherein user U₀ may be representative of user 5 of FIG. 1. For example, account manager 274 enables authentication and access by user U₀ to GCS 201. Account manager 274 stores information about member users. For instance, a user profile for each member user may be managed by account manager 274. In that manner, member information can be used by the account manager 274 for authentication purposes. For example, account manager 2274 may be used to update and manage user information related to a member user. Additionally, game titles owned by a member user may be managed by account manager 274. In that manner, video games stored in data store 264 are made available to any member user who owns those video games.

In one embodiment, a user, e.g., user U₀, can access the services provided by GCS 201 and social media providers 240 by way of user device 230 through connections over network 220. User device 230 can include any type of device having a processor and memory, wired or wireless, portable or not portable. In one embodiment, user device 230 can be in the form of a smartphone, a tablet computer, or hybrids that provide touch screen capability in a portable form factor. One exemplary device can include a portable phone device that runs an operating system and is provided with access to various applications (apps) that may be obtained over network 220, and executed on the local portable device (e.g., smartphone, tablet, laptop, desktop, etc.).

User device 230 includes a display 232 that acts as an interface for user U₀ to send input commands 236 and display data and/or information 235 received from GCS 201 and social media providers 240. Display 232 can be configured as a touch-screen, or a display typically provided by a flat-panel display, a cathode ray tube (CRT), or other device capable of rendering a display. Alternatively, the user device 230 can have its display 232 separate from the device, similar to a desktop computer or a laptop computer.

In one embodiment, user device 130 is configured to communicate with GCS 201 to enable user U₀ to play a video game. In some embodiments, the GCS 201 may include a plurality of virtual machines (VMs) running on a hypervisor of a host machine, with one or more virtual machines configured to execute a game processor module utilizing the hardware resources available to the hypervisor of the host. For example, user U₀ may select (e.g., by game title, etc.) a video game that is available in the video game data store 264 via the game selection engine 275. The video game may be played within a single player gaming environment or in a multi-player gaming environment. In that manner, the selected video game is enabled and loaded for execution by game server 205 on the GCS 201. In one embodiment, game play is primarily executed in the GCS 201, such that user device 230 will receive a stream of game video frames 235 from GCS 201, and user input commands 236 for driving the game play is transmitted back to the GCS 201. The received video frames 235 from the streaming game play are shown in display 232 of user device 230. In other embodiments, the GCS 201 is configured to support a plurality of local computing devices supporting a plurality of users, wherein each local computing device may be executing an instance of a video game, such as in a single-player video game or multi-player video game. For example, in a multi-player gaming environment, while the video game is executing locally, the cloud game network concurrently receives information (e.g., game state data) from each local computing device and distributes that information accordingly throughout one or more of the local computing devices so that each user is able to interact with other users (e.g., through corresponding characters in the video game) in the gaming environment of the multi-player video game. In that manner, the cloud game network coordinates and combines the game plays for each of the users within the multi-player gaming environment.

In one embodiment, after user U₀ chooses an available game title to play, a game session for the chosen game title may be initiated by the user U₀ through game session manager 285. Game session manager 285 first accesses game state store in data store 140 to retrieve the saved game state of the last session played by the user U₀ (for the selected game), if any, so that the user U₀ can restart game play from a previous game play stop point. Once the resume or start point is identified, the game session manager 285 may inform game execution engine in game processor 210 to execute the game code of the chosen game title from game code store 261. After a game session is initiated, game session manager 285 may pass the game video frames 235 (i.e., streaming video data), via network interface 290 to a user device, e.g., user device 230.

During game play, game session manager 285 may communicate with game processor 210, recording engine 271, and tag processor 273 to generate or save a recording (e.g., video) of the game play or game play session. In one embodiment, the video recording of the game play can include tag content entered or provided during game play, and other game related metadata. Tag content may also be saved via snapshots. The video recording of game play, along with any game metrics corresponding to that game play, may be saved in recorded game store 262. Any tag content may be saved in tag data stored 263.

During game play, game session manager 285 may communicate with game processor 204 to deliver and obtain user input commands 236 that are used to influence the outcome of a corresponding game play of a video game. Input commands 236 entered by user U₀ may be transmitted from user device 230 to game session manager 285 of GCS 201. Input commands 236, including input commands used to drive game play, may include user interactive input, such as including tag content (e.g., texts, images, video recording clips, etc.). Game input commands as well as any user play metrics (how long the user plays the game, etc.) may be stored in game network user store. Select information related to game play for a video game may be used to enable multiple features that may be available to the user.

Because game plays are executed on GCS 201 by multiple users, information generated and stored from those game plays enable any requesting user to experience the game play of other users, particularly when game plays are executed over GCS 201. In particular, GCS 201 is configured to save snapshots generated by the game play of users playing video games through GCS 201. In the case of user U₀, user device provides an interface allowing user U₀ to engage with the video game during the game play. Snapshots of the game play by user U₀ is generated and saved on GCS 201.

Also, user device 130 is configured to provide an interface allowing user U₀ to preview the video game using the snapshots. For example, by viewing snapshot images of game plays or one or more users, user U₀ is able to preview one or more portions of the video game at any point in the video game, as long as another user has already played through that point and generated a snapshot. Moreover, as will be described in more detail below snapshots and/or snapshot images presented in a timeline may provide to a user a preview into the video game at various points without necessarily playing the video game at those points. For instance, by viewing snapshots and/or snapshot images, the timeline may illustrate in which direction a video game would follow at a particular point or points in the video game. If the direction leads to a dead-end or undesirable result to the user, the user may choose to avoid taking paths in the video game leading to those points corresponding to the snapshots. On the other hand, if the direction leads to a desirable result (e.g., loot, interesting battle or interaction, etc.), the user may choose to take paths in the video game leading to those points corresponding to the snapshots. In addition, user device 130 is configured to provide an interface allowing user U₀ to navigate through the video game. For example, as will be described in more detail below snapshots may be used to generate a node graph showing paths taken by one or more users progressing through the video game. The user may interface with the node graph to display the snapshots and/or snapshot images at selected nodes in the node graph which provides to a user a preview into the video game at various nodes of the video game without necessarily playing the video game at those points. If the direction in the node graph leads to a dead-end or undesirable result to the user, the user may choose to avoid taking node paths in the video game leading to those points corresponding to the nodes. On the other hand, if the direction in the node graph leads to a desirable result, the user may choose to take node paths in the video game leading to those points corresponding to the nodes.

Further, user device 130 is configured to provide an interface that enables the jumping to a selected point in the video game using a snapshot generated in the game play of user U₀ or another user. In that manner, user U₀ is able to experience the game play of any other user, or go back and review and/or replay his or her own game play. That is, a requesting user, via a snapshot of a corresponding game play, plays the video game using the characters used in and corresponding to that game play.

FIGS. 3-8 are described within the context of a user playing a video game. In general, the video game may be any interactive game that responds to user input. For purposes of illustration only, the video game described in relation to FIGS. 3-8 may be an adventure game, wherein the character encounters various obstacles and challenges while traveling through the world. The character may be traveling on foot, or through any mechanized means in the video game. In addition, the character may encounter one or more challenges that could lead to delays when progressing through the video game from start to end.

Throughout the specification, the use of time in one or more timelines of FIGS. 3-8 is meant to show progression through the video game, and not necessarily a measure of how long the user plays the video game.

FIG. 3A is an illustration of a timeline 310 a displayed during game play of a video game by a user, wherein the timeline shows snapshot images of game play of the user, as well as snapshot images of game play of another user, in accordance with one embodiment of the present disclosure. Further, the timeline 310 a is generated by timeline generator 213 of game processor 210 of game server 205 of the GCS 201, in one embodiment. Timeline 310 a can be used to quickly preview previous game play by the user, as well as game play of one or more other users.

Window 350 a and timeline 310 a are displayed while the game executing engine 211 of game processor 210 instantiates an instance of the video game. For example, window 300 shows a rendered image 305 during the game play of a user for a particular video game. The rendered image is associated with a current point in the progression of the user through the video game. As shown, in rendered image 305 the character 306 representing the user in the game play is on a motorcycle. The character 306 is riding on a road through mountainous terrain, but has encountered a rock fall 307. In the game play of the user, the character is chosen to be male with short, spiky hair as shown in rendered image 305. At this point, the user may be frustrated with the progress through the video game, and may want to explore avenues to maneuver around the rock fall. For instance, the user may want to preview game plays of other users to explore solutions allowing the user to go past the rock fall, and to explore future experiences in the video game at points beyond the current progression of the user as represented by the rendered image 305. Exploration of these other game plays may be enabled through the timeline 310 a, and more specifically through snapshot images, and their corresponding snapshots, as displayed in timeline 310 a. As previously introduced, a snapshot enables execution of an instance of a corresponding video game beginning from a point in the video game associated with the corresponding snapshot. In particular, further selection of a snapshot image presented in a timeline or node in a node graph by a user enables the jump executing engine 216 of game processor 210 to access the corresponding snapshot, instantiate another instance of the video game based on the snapshot, and execute the video game beginning at a point in the video game corresponding to the snapshot.

Timeline 310 a is displayed in window 350 a. In general, multiple timelines including snapshot images of one or more game plays of one or more users may be displayed in window 350 a. As shown in FIG. 3A, window 350 a may display a single timeline 310 a, wherein timeline 310 a includes snapshot images of game play by the user, as well as snapshot images of game play by another user. The snapshot images are presented in thumbnails and/or windows and displayed in relation to the currently rendered image of the video game in the game play of the user. For example, snapshot images occurring before a point in the video game represented by currently rendered image 305 may be displayed to the left of blank thumbnail 340 c, and snapshot images occurring after the point may be displayed to the right of thumbnail 340 c. Window 350 a may also display additional timelines including snapshot images of one or more game plays of a video game by one or more users, as will be further described in relation to FIG. 3B. The timelines show progression through the video game, and not necessarily a measure of how long the user plays the video game.

In particular, timeline 310 a includes snapshot images for the game play by the user. For example, a plurality of snapshot images (e.g., images 340 a, 340 b, . . . ) corresponding to snapshots captured during the game play by the user is displayed in timeline 310 a in thumbnails and/or windows. Viewed together the snapshot images give a quick history of the game play of the user. For instance, snapshot image 340 a shows the character 306 jumping a motorcycle off a ramp or cliff. At this point in the game, the character 306 has 2 possible lives, as indicated by the two circles in the upper left corner of snapshot image 340 a. Thereafter in the progression of the user through the video game, snapshot image 340 b shows the character 306 (still with two possible lives) riding through the motorcycle through the forest, and is approaching a mountain. The currently rendered image 305 shown in window 300 shows that the character 306 has reached the mountain, and has approached the rock fall 307. At this point, character 306 has two possible lives.

Because rendered image 305 is currently displayed, and represents the progression of the user through the video game, only snapshot images representing previous game play by the user are displayed. These snapshot images typically represent points in the game that occur before a point represented by the currently displayed rendered image 305. For illustration purposes only, the total number of possible lives for a character gives a rough estimate of the progress through the video game for a user. However, some video games may allow for the user to progress back and forth, as the user plays the video game. In any case, only snapshot images corresponding to previously rendered images may be displayed in timeline 310 a for the user, in one embodiment. These snapshot images are displayed in relation to the currently rendered image 305 in timeline 310 a, which is represented by blank thumbnail 340 c. For example, the snapshot images may be displayed to the left of blank thumbnail 340 c. Further ordering may be achieved between two snapshot images by displaying a first snapshot image captured at first point in the video game to the left of a second snapshot image occurring at a second point that occurs after the first point in the general progression of a user through the video game. In another implementation, thumbnail 340 c may be populated with rendered image 305 to show current progress of the user in the timeline 310 a.

Snapshot images representing points in the video game occurring before the currently rendered image 305 may be displayed in a manner distinguishing them from snapshot images representing points in the video game occurring after the currently rendered image 305, i.e., future points. In one embodiment, the snapshot images may be grayed out. That is, the snapshot images corresponding to points occurring before the currently rendered image 305 are displayed with a lower intensity and/or resolution than snapshot images corresponding to points occurring later in progression through the video game. Other embodiments are supported, such as showing the snapshot images with cross-hatching, or blurring the snapshot images, etc.

Further, timeline 310 a includes snapshot images for the game play by another user. This other user may be a friend which is discovered through social media manager 295, in one embodiment. The snapshot images may also correspond to game play of random users, or users of high interest, such as users with high scores in the video game. For purposes of illustration only, in the examples provided in relation to FIGS. 3-8, these other users are referred to as friends of the current user, such as a first friend F1, a second friend F2 and a third friend F3. The first friend F1 is playing a character 308 that is depicted as a woman with long hair. Second friend F2 is playing a character 309 that is depicted as a male with full head of hair. Third friend F3 is playing a character 303 that is depicted as a bald male.

In particular, timeline 310 a includes snapshot images for the game play by a second user (e.g., friend F1 playing a woman character 308). For example, a plurality of snapshot images (e.g., images 360 d, 360 e, 360 f, . . . ) corresponding to snapshots captured during the game play by the second user is displayed in timeline 310 a in thumbnails and/or windows. These snapshot images are displayed in relation to the currently rendered image 305. For example, snapshot images 360 d, 360 e, and 360 f displayed to the right of blank thumbnail 340 c occur at points in the video game after the currently rendered image 305. Though not shown in timeline 310 a, snapshot images occurring at a point in the video game around or before the currently rendered image (e.g., snapshot images 360 a, 360 b, and 360 c) may also optionally be shown, and are further described in relation to timeline 310 b displayed in window 350 b of FIG. 3B.

Viewed together the snapshot images give a quick history of the game play of the second user (e.g., friend F1) at points in the future that occur after the currently rendered image 305. For instance, snapshot image 360 d shows the character 308 contemplating how to cross a river, and having three possible lives. Progressing further along in the video game, the character 308, now with four possible lives, is battling a bear in snapshot image 360 e. Progressing even further along in the video game, character 308, now with five possible lives, is shown driving a car through the desert in snapshot image 360 f.

In one embodiment, a timeline may be modified depending on the progression by the user through the video game, and the available snapshot images. For example, snapshot images that occur too far in the past (e.g., for the user or other users) in relation to the currently rendered image 305 may not be displayed, and snapshot images that occur too in the future (e.g., for the other users) may also may not be displayed. Further, as other users are changed and/or replaced, corresponding snapshot images are updated in the timeline.

FIG. 3B is an illustration of multiple timelines displayed during game play of a video game by a user, wherein a timeline shows snapshot images of game play of the video game of one or more users, in accordance with one embodiment of the present disclosure. The timelines are displayed in window 350 b. In one embodiment, window 350 b is displayed along with the currently rendered image 305 in the game play of a user. For example, timelines 310 b, 320 and 330 are displayed in window 350 b, and are generated by timeline generator 213 of game processor 210 of game server 205 of the GCS 201, in one embodiment. The timelines can be used to quickly preview previous game play by the user, as well as game play of one or more other users (e.g., friends, random users, users of interest, etc.).

As shown, timeline 310 b includes snapshot images (e.g., 340 a, 340 b, . . . ) of game play by the user, as previously discussed in relation to FIG. 3A. These snapshot images may be displayed in thumbnails as shown in FIG. 3B, and are arranged in relation to the currently rendered image 305. For instance, these snapshot images are displayed to the left of the currently rendered image 305, and arranged generally with a first snapshot image located to the left of later occurring snapshot image, as previously described.

Further, timeline 310 b includes a plurality of snapshot images (360 a, 360 b, 360 c, 360 d, 360 e, 360 f, . . . ) corresponding to snapshots captured during the game play by the second user (e.g., a first friend F1 playing woman character 308). These snapshot images are displayed in timeline 310 b in thumbnails, and are arranged in relation to the currently rendered image 305, as previously described. More particularly, snapshot images, corresponding to game play by friend F1, occurring at a point in the video game around or before the currently rendered image (e.g., snapshot images 360 a, 360 b, and 360 c) may also be optionally included below the snapshot images (e.g., 340 a, 340 b, . . . ) of the user. Snapshot images (e.g., 360 a, 360 b, . . . ) occurring at points in the video game progression before the currently rendered image may be arranged to the left of blank thumbnail 340 c. As an indication of game progress, snapshot images 360 a-c show the character having two possible lives. Snapshot image 360 c occurs approximately at the same point of progression through the video game as currently rendered image 305, and is located approximately below blank thumbnail 340 c. For example, both snapshot image 360 c and currently rendered image 305 show corresponding characters each having two possible lives. Furthermore, snapshot images in timeline 310 b may be arranged generally such that a first snapshot image is located to the left of a later occurring snapshot image, as previously described. Arrow 399 may link the snapshot images associated with the second user, friend F1.

Viewed together, the snapshot images give a quick history of the game play of the first friend F1. For instance, the character 308 of friend F1 is first shown riding a motorcycle on a downtown city street in snapshot image 360 a. Thereafter in the progression of friend F1 through the video game, snapshot image 360 b shows the character 308 (having two possible lives) riding through the motorcycle through the forest, and is approaching a mountain. Progressing further along in the video game, the character 308 is riding the motorcycle on a mountain road in snapshot image 360 c. For example, the character 308 of friend F1 may have maneuvered around the rock fall that the character 306 of the user is currently encountering in rendered image 305. Later, the character 308 (having three possible lives) is shown approaching a river in snapshot image 360 d. Progressing still further along, the character 308 (having four possible lives) is battling a bear in snapshot image 360 e, and then later the character 308 (having five possible lives) is shown driving a car through the desert in snapshot image 360 f.

Window 350 b shows another timeline 320 that is associated with the game play of another user, such as a second friend F2. As shown, timeline 320 includes snapshot images (370 a, 370 b, 370 c, 370 d, 370 e . . . ) of game play by friend F2. These snapshot images may be displayed in thumbnails, and are arranged in relation to the currently rendered image 305, in one embodiment. For instance, snapshot images (e.g., 370 a, 370 b, . . . ) occurring at points in the video game progression before the currently rendered image are arranged approximately to the left of blank thumbnail 340 c. These snapshot images may be readily identified by graying out the displayed content, as previously described. Snapshot image 370 c occurs approximately at the same point of progression through the video game as currently rendered image 305, and is located approximately below blank thumbnail 340 c. Snapshot images (e.g., 370 d, 370 e, . . . ) occurring at points in the video game progression after the currently rendered image are arranged approximately to the right of blank thumbnail 340 c. Furthermore, snapshot images in timeline 320 may be arranged generally such that a first snapshot image is located to the left of a later occurring snapshot image, as previously described.

Viewed together, the snapshot images give a quick history of the game play of the second friend F2. For instance, the character 309 (having two possible lives) of friend F2 is first shown fording a river in snapshot image 370 a. Thereafter in the progression of friend F2 through the video game, snapshot image 370 b shows the character 309 traversing through a forest on foot, and approaching a range of taller mountains. Still progressing further along, the character 309 (having two possible lives) is shown summiting a false mountain peak in snapshot image 370 c. Still later, the character 309 (having four possible lives) is shown free climbing a face of a mountain in snapshot image 370 d, and then later is shown crossing a lake by boat in snapshot image 370 e.

Window 350 b shows another timeline 330 that is associated with the game play of another user, such as a third friend F3. As shown, timeline 330 includes snapshot images (380 a, 380 b, 380 c, 380 d, 380 e, 380 f, . . . ) of game play by friend F3. These snapshot images may be displayed in thumbnails, and are arranged in relation to the currently rendered image 305, in one embodiment. For instance, snapshot images (e.g., 380 a, 380 b, . . . ) occurring at points in the video game progression before the currently rendered image are arranged approximately to the left of blank thumbnail 340 c. These snapshot images may be readily identified by graying out the displayed content, as previously described. Snapshot image 380 c occurs approximately at the same point of progression through the video game as currently rendered image 305, and is located approximately below blank thumbnail 340 c. Snapshot images (e.g., 380 d, 380 e, 380 f, . . . ) occurring at points in the video game progression after the currently rendered image are arranged approximately to the right of blank thumbnail 340 c. Furthermore, snapshot images in timeline 320 may be arranged generally such that a first snapshot image is located to the left of a later occurring snapshot image, as previously described.

Viewed together, the snapshot images give a quick history of the game play of the third friend F3. For instance, the character 303 (having two possible lives) of friend F3 is first riding a motorcycle through the forest in snapshot image 380 a. Thereafter in the progression of friend F3 through the video game, snapshot image 380 b shows the character 303 (having two possible lives) fording a river. Still progressing further along, the character 3039 (having three possible lives) is shown kayaking down a waterfall in snapshot image 380 c. Still later, the character 303 is shown crossing a lake by motor boat in snapshot image 380 d, and then in snapshot image 390 e the character 303 is shown docking boat. Even later in the progression, character 303 (having five possible lives) is shown flying an airplane to the next destination in snapshot image 380 f.

Though referred to as different timelines, all the timelines in window may be referred as one timeline belonging to the user playing the video game. In addition, timelines associated with other users (e.g., timelines 320, 330, and portions of 310) may be replaced with timelines of new users, in one embodiment. In that manner, snapshot images of rotating users may be shown to the user. In another embodiment, more timelines may be shown, or a lesser number of timelines may be shown for clarity.

In still another embodiment, a timeline in windows 350 a or 350 b may display snapshot images that are associated with a completely different game or content. For example, the timeline may be shown to entice the user to preview and try another video game or to view other content. In another embodiment, one or more timelines of one or more users may be shown to a new user interested in playing a video game. The new user may not necessarily be playing the video game, but is interested in previewing the game plays of others playing the video game. In other cases, the new user may have just started the video game. As an illustration, a method for previewing a gaming world may be implemented in a video game having linear or non-linear progression, in accordance with one embodiment of the present disclosure. In particular, the method includes capturing a plurality of snapshots generated from a plurality of game plays of a plurality of users playing the video game. As previously described, each snapshot enables execution of an instance of the video game beginning from a point in the video game corresponding to that snapshot, such as where in the video game that snapshot was captured. The method includes generating for display a first timeline of a first user, wherein the first timeline includes a plurality of first thumbnails including a plurality of first snapshot images of the game play of the first user progressing through the video game. The method may include the presentation of other timelines. For instance, the method may include generating for display a second timeline of a second user, wherein the second timeline includes a plurality of second thumbnails including a plurality of second snapshot images of game play of the second user progressing through the video game

In embodiments, the timelines generated for one or more users may be associated with a video game that has a linear progression, multiple linear progressions, non-linear progression, or a combination thereof. For example, in a video game having a linear progression, points in the video game may occur linearly in relation to each other, such that a first point is before a second point in a corresponding linear progression. A fork may present two or more linear extensions, each of which is associated with its own linear progression. In other embodiments, in a video game having non-linear progression, points in the video game may not have any relation to each other because of the non-linearity in terms of progressing through a video game. For instance, the non-linear video game may have multiple storylines that operate in parallel without any relation to each other, such as a video game that explores different parts of the world or different universes, and may or may not have an overriding objective. In that case, the timelines shown for a particular user may correspond to the same storyline that the user is involved with, or may correspond to other storylines. Further, the storylines may operate without any relation to each other, such that even in one part of the world being explored or a universe being explored corresponding storylines may be generated in a non-linear fashion. In the case of a non-linear video game, snapshots shown in a particular timeline for another player may be arbitrarily arranged in relation to a currently rendered image for the user, a timeline for the user, or timelines for other players. In still other embodiments, a video game may include portions of linearity and non-linearity. For example, in the case of a video game that explores different parts of the world or different universes in a non-linear fashion, the exploration within a particular part of the world or one universe may follow a linear progression.

FIG. 4A is an illustration of timeline 310 a presented in window 350 a, wherein timeline 310 a is first introduced in FIG. 3A, showing snapshot images of game play of a video game of at least one user, wherein selection of a snapshot enables an enlarged view of the snapshot image, in accordance with one embodiment of the present disclosure. As previously described, window 300 shows the currently rendered image 305 of the game play of the video game by a user. Timeline 310 a includes snapshot images (340 a, 340 b, . . . ) of game play by the user (playing character 306) at points in the progression through the video game occurring before the currently rendered image 305. Timeline 310 also includes snapshot images (360 d, 360 e, 360 f, . . . ) of game play by another user (e.g., friend F1 playing character 308) at points in the progression through the video game occurring after the currently rendered image 305.

More particularly, the snapshot images are presented in the timeline 310 a via thumbnails. As such, depending on the size of the thumbnails, the rendered images may be too small to show much detail. The user may select a snapshot for enlargement. For example, the user may roll cursor 490 a over the thumbnail presenting snapshot image 360 e, in one embodiment. Other methods are supported for selection of a snapshot image for enlargement, such as touching the displayed snapshot image on a touchscreen. Window 410 is generated and displayed in approximately the same area of the selected thumbnail. Window 410 displays the rendered snapshot image 360 e, wherein window 410 is of a sufficient size to give the user a better view of snapshot image 360 e.

For purposes of clarity, a blow up of the snapshot image 360 e is presented in box 420. However, in one embodiment, through further selection of window 410 and/or snapshot image 360 e, box 420 may be displayed as a window showing an even larger snapshot image 360 e than that presented in window 410. As previously described, snapshot image 360 e is associated with the game play of another user (e.g., friend F1 playing woman character 308), and shows the character 308 encountering a bear. By scrolling through the snapshot images presented in timeline 310 a and viewing the enlarged images, the user can preview the game play of friend F1. In that manner, further selection by the user of a selected snapshot image presented in timeline 310 a and/or a node in a node graph (described below) by a user enables the jump executing engine 216 of game processor 210 to access the corresponding snapshot, instantiate another instance of the video game based on the snapshot, and execute the video game beginning at a point in the video game corresponding to the snapshot. For example, the user may experience the game play of another user (e.g., friend F1), or go back and re-experience and/or replay his or her own game play.

FIG. 4B is an illustration of one or timelines presented in window 350 b, each of which show snapshot images of game play of a video game of at least one user, wherein selection of a snapshot enables an enlarged view of the snapshot image, in accordance with one embodiment of the present disclosure. The timelines shown in FIG. 4B were previously described in relation to FIG. 3B, and include timelines 310 b, 320 and 330. In particular, timeline 310 b includes snapshot images of game play by the user playing character 306 at points in the progression through the video game occurring before the currently rendered image 305. Timeline 310 b further includes snapshot images corresponding to snapshots captured during the game play by friend F1 playing character 308 at points in the progression through the video game occurring before, approximately concurrent, and after the currently rendered image 305. The snapshot images are presented in thumbnails, in one embodiment. Timeline 320 includes snapshot images (370 a, 370 b, 370 c, 370 d, 370 e . . . ) corresponding to snapshots captured during game play by friend F2 playing character 309 at points in the progression through the video game occurring before, approximately concurrent, and after the currently rendered image 305. Timeline 330 includes snapshot images corresponding to snapshots captured during the game play by friend F3 playing character 303 at points in the progression through the video game occurring before, approximately concurrent, and after the currently rendered image 305. As shown in FIG. 4B, interaction with snapshot images for timeline 320 are further described, and as such snapshot images in timelines 310 b and 330 are not labeled for ease of understanding.

More particularly, the snapshot images are presented in the timelines 310 b, 320 and 330 via thumbnails. As such, depending on the size of the thumbnails, the rendered images may be too small to show much detail. The user may select a snapshot in any of the timelines for enlargement. While FIG. 4A illustrates selection of a snapshot image in a timeline associated with the user, FIG. 4B illustrates the selection of a snapshot image for enlargement in one of the timelines corresponding to a friend. For example, the user may roll cursor 490 b over the thumbnail presenting snapshot image 370 d in timeline 320, in one embodiment. Other methods are supported for selection of a snapshot image for enlargement, such as touching the displayed snapshot image on a touchscreen. Enlarged window 460 is generated and displayed in approximately the same area of the selected thumbnail. Window 460 displays the rendered snapshot image 370 d, wherein window 460 is of a sufficient size (e.g., larger than the corresponding thumbnail) to give the user a better view of snapshot image 370 d.

For purposes of clarity and understanding, a blow up of the snapshot image 370 d is presented in box 465. However, in one embodiment, through further selection of window 460 and/or snapshot image 370 d, box 465 may be displayed as a window showing an even larger snapshot image 370 d than that presented in window 460. As previously described, snapshot image 370 d is associated with the game play of friend F2, and shows the character 309 free climbing up a sheer rock face. By scrolling through the snapshot images presented in timeline 320 and viewing the enlarged images, the user can preview the game play of friend F2. In that manner, further selection by the user of a selected snapshot image presented in timeline 320 or node in a corresponding node graph (described below in further detail) by a user enables the jump executing engine 216 of game processor 210 to access the corresponding snapshot, instantiate another instance of the video game based on the selected snapshot, and execute the video game beginning at a point in the video game corresponding to the selected snapshot.

FIG. 5A is an illustration of a node graph 530 of game play of a video game, wherein the node graph is displayed along with a timelines 310 b 320 and 330 in window 350 b, first introduced in FIG. 3B, during game play of a video game by a user. In particular, timeline 310 b shows snapshot images of game play of the user playing character 306 at points, as well as snapshot images of game play of another user (e.g., friend F1 playing character 308), timeline 320 shows snapshot images of game play by friend F2 playing character 309, and timeline 330 shows snapshot images of game play by friend F3 playing character 303. The snapshot images in each of the timelines are presented in relation to the currently rendered image 305 (e.g., as represented by blank thumbnail 340 c), as previously described. Window 300 also shows the currently rendered image 305 of the game play of the video game by a user.

As shown in FIG. 5A, snapshot image 360 e is selected (e.g., through interaction of a corresponding thumbnail) for enlargement in timeline 310 b. Snapshot image 360 e is associated with the game play of friend F1 at a point in the game that occurs after (e.g., in the future) the currently rendered image 305. In particular, the user may roll cursor 590 a over the thumbnail presenting snapshot image 360 e in timeline 310 b, in one embodiment. Other methods are supported for selection of a snapshot image for enlargement, such as touching the displayed snapshot image on a touchscreen. Window 410 shows the enlarged snapshot image 360 e, as previously described.

Further, node graph 530 is presented in window 510. In one embodiment, node graph 530 includes a plurality of nodes that correspond to the various paths a character may choose as the user progresses through the video game. In one embodiment, node graph 530 may be presented in window 510 as a universal graph showing all the nodes of the video game, as will be further described in FIG. 5B. In one embodiment, node graph 530 may be presented to include a subset of nodes of the universal graph, which shows nodes of particular interest, as will be further described in relation to FIG. 5C. For example, the subset of nodes may correspond to snapshot images displayed in one or more timelines.

Though window 510 is shown in the bottom right corner, it is understood that window 510 may be located anywhere in window 300. Further, window 510 may be of a sufficient size to provide information suitable for viewing. Further selection may display window 510 as an enlarged window within window 300, or on a full screen.

As shown, node 572 in node graph 530 may be automatically highlighted (e.g., bolded, enlarged, colored, etc.) in response to the user selecting snapshot image 360 e in timeline 310 a for enlargement. Node 572 corresponds approximately to the location of the snapshot image 360 e, and gives context within the universe of the video game for snapshot image 360 e. That is, because the user is interested in snapshot image 360 e, through selection of the snapshot image 360 e in timeline 310 b, window 410 is presented showing a larger view of snapshot image 360 e, and node 572 is highlighted in node graph 530. Node 572 may also be highlighted through manual selection of the node in node graph 530 by the user.

In summary, node graph 530 may be presented in window 510 automatically or in response to a user request, wherein the node graph 530 includes a subset of nodes that correspond to the snapshot images presented in timeline 310 a. Further, node 572 may be presented and highlighted, wherein node 572 shows the approximate location of a point in the game play of a video game corresponding to snapshot image 360 e. In addition, the snapshot image 360 e corresponding to node 372 may be presented in window 520, wherein window 520 is larger than window 410, and may show an even larger view of snapshot image 360 e.

In that manner, the user is presented with a multi-dimensional view of the video game. For example, the user is presented with a current view of his or her own game play via rendered image 305. The game play of the user (e.g., through rendered image 305 and snapshot images in a user timeline) is also presented alongside one or more timelines of one or more users showing a quick preview of the game play of other users throughout various points of progression in the video game. The snapshot images may be presented with a node graph showing paths through the video game associated with snapshot images in timelines, or all possible paths in the video game.

FIG. 5B is an illustration of a universal node graph 550 or node tree showing all possible paths available in a video game, in accordance with one embodiment of the present disclosure. The universal node graph 550 may be displayed in window 510 of FIG. 5A. For example, the video game may include a start point as indicated by node 551, and an end point as indicated by node 552. Though one end point is shown, generally a universal node graph may have one or more end points, representing one or more options for finishing a video game. Further, a video game may have one or more start points that are represented in a corresponding universal node graph.

Universal node graph 550 includes a plurality of nodes (e.g., logical nodes) that define the various logical paths (also referred to as “paths” in the specification) a character may choose as the user progresses through the video game. For example, logical path 511 is defined between nodes 502 and 503. In addition, the universal node graph 550 may also include a subset of nodes. For example, node graph 530, which is a subset of universal node graph 550, includes nodes and paths which correspond to snapshot images displayed in timeline 310 b of FIG. 5B. Node graph 530 is also shown in window 510 of FIG. 5A.

Multiple logical paths may be configured to progress through universal graph 550 from node to node in a linear fashion. For example, the user moves in a linear fashion through node graph 530 between nodes 501 to 503 (e.g., from node 510 to node 502 and then to node 503) along logical paths 514 and 511. That is, no other logical paths can be taken when traversing between nodes 501 and node 503.

In addition, multiple logical paths may be configured to progress from node to node in a non-linear fashion. For example, the user moves in a non-linear fashion through node graph 550 when reaching node 503 along logical path 511. In particular, two options are available at node 503, wherein in a first option a character may take path 512, and in a second option the character may take path 513. Different outcomes may result from taking the two different paths.

Progression through the video game may generally be defined by a universal time line 529 that begins at a time or mark 521 associated with start point 551, and ends at a time or mark 522 associated with end point 552. The use of time in the timeline 529 is meant to show progression through the video game, and not necessarily a measure of how long the user plays the video game. As the user moves from node to node through universal node graph 530, a representative time or mark may be located on timeline 529. For example, node 501 may be represented as mark 523 and node 503 may be represented as mark 524 in timeline 529. Progress may be measured along timeline 529 from left to right. As an illustration, node 501 occurs before node 503 in the progression through the video game. As such, mark 523 representing node 501 is displayed to the left of mark 524 representing node 503. Further, progression may be further illustrated in association with timeline 529 and node graph 550 through various character values associated with the user, as previously described. For example, progress may be measured by how many possible lives are available to a character, or how many points or cash the character has accumulated.

FIG. 5C is an expanded illustration of a node graph 530, first introduced in FIG. 5A, showing the hierarchy of snapshot nodes generated in association with snapshots captured during game play of a video game, in accordance with one embodiment of the present disclosure. In one embodiment, node graph 530 is displayed along with one or more timelines (e.g., timelines 310 b, 320, and 330) during game play of a video game by a user. For example, node graph 530 may be displayed in window 510 of FIG. 5A, or may be displayed in an even larger window. An expanded view of node graph 530 displayed in window 510 is shown in FIG. 5C for illustration. An outline of window 350 b is presented in FIG. 5C for referencing snapshot images and corresponding snapshot nodes in node graph 530.

In particular, snapshot nodes correspond to points in game play of a video game where a snapshot has been captured. In general, snapshots may be captured at the nodes of the universal node graph 550. As such, snapshot nodes may align with nodes in universal node graph 550. However, some snapshot nodes may not align with nodes in a universal graph 550, such as when a snapshot has been captured between two nodes of the universal graph (e.g., in the middle of a logical path). For example, snapshot node 561 may be captured between two nodes (corresponding to nodes 560 and 562) in the universal node graph 550.

Node graph 530 includes a plurality of snapshot nodes that define the various actual paths that a character has taken during the game play of a corresponding user. For example, path 579 is defined between snapshot nodes 560 and 561. Path 579 is shown to have been taken in the game play of the user, as well as the game play of friend F1. Node graph 530 may show one or both of linear and non-linear paths, as defined in the game plays of one or more users.

Node graph 530 corresponds to snapshot images shown in timelines 310 b, 320 and 330 displayed in window 350, in one embodiment. For example, snapshot node 562 corresponds to box 340 c representing the currently rendered image 305 of the user, snapshot node 507 corresponds to snapshot image 360 e of friend F1, snapshot node 595 corresponds to snapshot image 370 a of friend F2, and snapshot node 565 corresponds to snapshot image 380 d of friend F3. In that manner, the user is presented with at least two or more views of the video game that are related, such as snapshot images and the currently rendered image in the timelines and the snapshot nodes in node graph 530. By cross referencing the currently rendered image 305 (along with its position in node graph 530) with other snapshot images (and their positions in node graph 530), the user is able to understand which paths are available to the user around a point in the video game associated with the currently rendered image. As such, the user is able to orient the character 306 within the universal node graph 550 and node graph 530 of the video game. In that manner, the user is able to navigate from one point to another point in the game. In one embodiment, though snapshot nodes are shown in FIG. 5C, node graph 530 may include nodes defining logical paths as defined by universal node graph 550.

More particularly, the paths taken by the user playing character 306 are shown by the line A that is dotted with fine resolution. For instance, the user has traveled between snapshot nodes 560, 561 and 562. From snapshot node 562, the character 306 of the user has taken a first route traveling up from snapshot node 562 through snapshot nodes 563 and 564, and a second route traveling downwards from snapshot node 562 through snapshot nodes 565 to 569 (e.g., from node 565 to node 566 to node 567 to node 568 and to node 569). The paths taken by the character 308 of friend F1 is shown by solid line B. For instance, character 308 of friend F1 has traveled along paths defined by snapshot nodes 560, 561, 562, 565, 570, 571,572, 573, and 574. Also, the paths taken by the character 308 of friend F2 is shown by line C that this dotted with coarse resolution. For instance, character 308 of friend F2 has traveled along paths defined by snapshot nodes 595, 596, 597, 598, 599, and 569. The paths taken by the character 303 of friend F3 is shown by line D, and shows that character 303 has traveled along paths defined by snapshot nodes 560, 581, 582, 583, 565, 584, 585, and 568.

In the progression of the video game, the user has taken paths that occur beyond or in the future of snapshot node 562, which corresponds to a point in the video game associated with the currently rendered image 305, but has retuned back to snapshot node 562. For example, the first route taken beyond snapshot node 562 and ending at snapshot node 564 may have reached a dead end. Also, the second route taken beyond snapshot node 562 and ending at node 569 may be unsatisfactory to the user. Snapshot images corresponding to snapshot nodes occurring beyond the currently rendered image 305 associated with the user are not shown in timeline 310 b, but may be shown in other embodiments.

The user has returned to node 562 in the game progression because the user may have heard rumors about an exciting part (encountering a bear) of the video game in this area, but has so far missed out on the action. The user believes that the exciting part is somehow reached through node 562. Embodiments of the present disclosure provide a way for the user to discover alternative paths through the video game by previewing game plays of other users, and laying out a potential route to take in the video game to reach an exciting part of the video game. For example, the user may preview the snapshot images of friend F1 playing character 308 in timeline 310 b, and discover that the bear encounter occurs in association with snapshot node 507, which corresponds to snapshot image 360 e. For reference, snapshot image 360 e is shown in box 509. Without the introduction of snapshot images presented in timelines, and/or the node graphs, the user would have a hard time previewing and/or discovering these areas of interest.

In particular, the user may have discovered snapshot image 360 e through viewing snapshot images in timeline 310 b, or may have discovered it through exploring the node graph 530. For example, tags 507 are shown next to snapshot node 572 in node graph 530 of FIG. 5C, which may have caught the attention of the user. By interacting with node 572 in node graph 530, a view of snapshot image 360 e may be presented to the user, such as in window 520 of FIG. 5A. Also, by selecting snapshot node 572 in node graph 530, the corresponding snapshot image 360 e in timeline 310 b may be highlighted (e.g., bolded) for attention. In that manner, the user may roll over the corresponding thumbnail to view an enlarged version of snapshot image 360 e. as previously described. In another implementation, if the node graph 530 is presented in its own dominant window (e.g., full screen, or overlaid window 300), interaction with snapshot node 572 may bring up snapshot image 360 e in another window (not shown).

After previewing game play of friend F1 and node graph 530, the user may wish to further explore the video game corresponding to snapshot image 360 e, and more particularly the game play of friend F1. As previously described, embodiments of the present disclosure enable the user to jump into the game play of friend F1. In particular, further selection by the user of a snapshot image 360 e via timeline 310 b or node graph 53 enables the jump executing engine 216 of game processor 210 to access the snapshot corresponding to snapshot image 360 e, instantiate another instance of the video game based on the snapshot, and execute the video game beginning at a point (now identified as a jump point) in the video game corresponding to the snapshot and its snapshot image 360 e. In that manner, the user may fully experience the video game at node 507 (encountering the bear) through the game play of friend F1. That is, the user jumps into the character 308 of friend F1 at jump node 572 and plays an instantiation of the game play of friend F1 beginning at the point of the video game corresponding to jump node 572 (which corresponds to snapshot image 360 e). As such, the user is able to jump into the game play at the most exciting part.

The user may decide to try to navigate to the same snapshot node 572 (bear encounter) previously captured by the game play of friend F1 after experiencing the game play of friend F1. Node graph 530 provides a view into the route taken by friend F1 in order to reach snapshot node 572 from the current position of the user, which is node 562 that is associated with the currently rendered image 305. For example, node graph shows that travel between nodes 562 and snapshot node 572 is possible via snapshot nodes 565 and 570.

FIG. 5D is an expanded illustration of a node graph 540 showing the hierarchy of snapshot nodes generated in association with snapshots captured during game play of a video game, in accordance with one embodiment of the present disclosure. The node graph 540 may be related to the node graph of FIG. 5C, but is used illustrate timelines used in a video game having portions of non-linear progression. For example, the game play within a level may be unrelated to game plays within another level. Also, game plays by different users within a single level may also be unrelated to each other in terms of progression through the video game.

As shown in node graph 540, the video game may include four different levels that are playable within the video game. Traversal between levels is possible in the video game. For example, the game plays of the user, friend 1, and friend 2 traverses through all four levels. The game play of friend 3 traverses through three levels. The game play of friend 4 traverses through level 2 only. The game play of friend 5 traverses through levels 3 and 4. As shown in FIG. 5D, the video game may be started at any level. For instance, the game play of friend 4 starts at level 2 and stays at level 2, and the game play of friend 5 starts at level 3 and continues to level 4 without extending to any other level. Though some game plays may overlap and show some portion of linear progression (e.g., the game plays of the user and friend 1), other game plays shown in FIG. 5D may show non-linear progressions through the video game. For instance, the game play and progression through the video game of friend 4 is unrelated to the game play and progression through the video game of friend 5.

FIG. 6A is an illustration of a cluster of snapshot nodes closely and linearly aligned with a selected snapshot node (e.g., the snapshot node 572 associated with snapshot image 360 e), wherein the snapshot node can be selected through a timeline 310 a or node graph 530, in accordance with one embodiment of the present disclosure. In particular, timeline 310 a includes snapshot images (340 a, 340 b, . . . ) of game play by the user at points in the progression through the video game occurring before the currently rendered image 305 (as represented by blank thumbnail 340 c. Timeline 310 a further includes snapshot images (360 d, 360 e, 360 f, . . . ) corresponding to snapshots captured during the game play by friend F1, as previously described. Further, each of the snapshot images correspond to a snapshot node, such as those presented in node graph 530.

Timeline 310 a may show selected snapshot images from the plurality of snapshots captured during the game play of the user and friend F1. The snapshots and snapshot images for friend F1 are used to illustrate the presentation of snapshot images with coarse and with higher resolution. For purposes of illustration, during the game play of friend F1 one-hundred snapshots are captured, and can be numbered 1 through 100 in the order that they were captured. The timeline 310 a may not have enough room to show all the snapshots images corresponding to the captured snapshots. As such, only a subset of snapshot images are presented in timeline 310. Further, snapshot images presented side-by-side in timeline 310 a may not be consecutively and/or sequentially captured. For instance, as shown in timeline 310 a of FIG. 6A, snapshot image 360 e is numbered 50 in the captured order, and the snapshot image directly to the right is snapshot image 360 f, which is numbered 60. As such, nine snapshot images were captured between snapshot image 360 e and snapshot image 360 f, but are not shown in timeline 310 a.

In one embodiment, a finer resolution of snapshot images may be generated and presented for display based on captured snapshots. In particular, further selection of a snapshot image, such as image 360 e, either through the timeline 310 a or through node graph 530 will enable the presentation of snapshot images with higher resolution. Further, in one embodiment, the snapshot images are presented in a node graph/tree configuration showing the paths that the user (e.g., friend F1) took during the game play. That is each snapshot image represents a node, and the snapshot images are presented in node graph configuration. For example, a window may display snapshot nodes via their corresponding images, wherein the snapshot nodes are captured sequentially before and/or after the snapshot corresponding to the selected snapshot image 360 e. Snapshot image 360 e corresponds to the jump point selected by the user to initiate the game play of friend F1, as previously described. Before or after being selected as a jump point, the user may want to see various snapshot images associated with snapshot image 360 e.

As shown in FIG. 6A, a linear progression of snapshot images are presented in various thumbnails in relation to the selected snapshot image 360 e. The snapshot image 360 e and its corresponding snapshot are also referenced as the jump point (JP), as previously described. The selected snapshot image 360 e and JP is associated with the snapshot numbered 50 in the order of captured snapshots. FIG. 6A shows that four snapshot images 610, 360 e, 615, and 620 are shown and correspond to one snapshot captured before JP (snapshot JP−1), JP, and two snapshots captured after JP (snapshot JP+1 and JP+2). That is, the snapshot images correspond to consecutively numbered snapshots 49-52. For example, snapshot image 610 (JP−1), snapshot image 360 e (JP), snapshot image 615 (JP+1), and snapshot image 620 (JP+2) are consecutively ordered 49-52. In that manner, the user is able to view at a higher resolution the action in the game play of friend F1 around snapshot image 360 e in a node graph configuration.

FIG. 6B is an illustration of a cluster of snapshot nodes closely and non-linearly aligned with a selected snapshot node (e.g., snapshot node 572 corresponding to snapshot image 360 e), wherein the snapshot node can be selected through a timeline 310 a or node graph 530 as previously introduced in relation to FIG. 6A, in accordance with one embodiment of the present disclosure. While FIG. 6A shows a linear progression through the video game around the jump point JP corresponding to snapshot image 360 e, FIG. 6B illustrates a non-linear progression through the video game around JP.

For example, the snapshot images are presented in a node graph/tree configuration showing the paths that friend F1 took during game play. That is each snapshot image represents a node, and the snapshot images are presented in node graph configuration. As shown in FIG. 6B, a non-linear progression of snapshot images are presented in various thumbnails in relation to the selected snapshot image 360 e, also referred to as JP with an order number of 50. Eight snapshot images are shown. In particular, snapshot image 605 corresponds to the snapshot node JP−2 with order 48. Also, snapshot image 610 corresponds to snapshot node JP−1 with order 49, wherein snapshot node JP−1 is a decision node showing a non-linear configuration. Two choices are available, as represented by order numbers 50A-B. One choice stemming from snapshot node JP−1 goes to snapshot image 613 with order 50B. The other choice stemming from snapshot node JP−1 routes to snapshot node JP, which corresponds to snapshot image 360 e and order number 50A. This route continues through consecutively numbered snapshot JP+1 (related to snapshot image 615 and order number 51) and snapshot JP+2 (related to snapshot image 620 and order number 52).

FIG. 6C-F are illustrations of snapshot images corresponding to a cluster of snapshot nodes closely aligned with a selected snapshot node and described in relation to FIGS. 6A-B, in accordance with one embodiment of the present disclosure. For example, FIG. 6C illustrates snapshot image 610 and shows the character 308 used in the game play of friend F1 first encountering the bear as it exits its cave. Snapshot image 610 corresponds to a snapshot node JP−1 with order number 49. FIG. 6D illustrates snapshot image 360 e (related to snapshot node JP and order number 50) and shows the character 308 engaging in close contact with the bear. The character 308 is shown handling a coiled rope that is presumably the only tool and/or weapon available to character 308. FIG. 6E illustrates snapshot image 615 (related to snapshot node JP+1 and order number 51) and shows that the character 308 has subdued the bear by tying each of the legs of the bear to a tree using the rope. FIG. 6F illustrates snapshot image 620 (related to snapshot node JP+2 and order number 52) and shows the character 308 enjoying the fruits of her victory over the bear: a weapon and other reward items (e.g., coins, precious stones, etc.) are available for the taking.

FIG. 7 is an illustration of snapshots captured during game play of a video game, and the storing of each of those snapshots as a separate master file of a data store 750, in accordance with one embodiment of the present disclosure. These master files are not automatically erased or overwritten as the user progresses through the video game, as is typical in the industry. In that manner, information and metadata related to each snapshot can be readily accessed at any time in order to present snapshot images (e.g., in timelines), node graphs, and to enable jumping to a jump point in the game play of the same or other user.

For example, a plurality of snapshots is captured in relation to game play of a particular user. The snapshots are numbered consecutively in the order of capture (i.e., 1-N). As shown in FIG. 7, at least snapshot 711 (order 20), snapshot 712 (order 31), snapshot 713 (order 32), and snapshot 714 (order 33) are captured.

Each snapshot includes information and/or metadata sufficient to load and execute an instance of the video game beginning at a point in the video game corresponding to the snapshot. For example, each snapshot includes at least game state data stored in database 145, snapshot image data stored in database 146, random seed data stored in database 143, and user saved data stored in database 141, as previously described. In one embodiment, metadata includes input commands used to drive an instance of the video game at and between two consecutively ordered snapshots. Each snapshot is stored in a corresponding master file in data store 750, wherein the master file corresponding to a particular snapshot may include pointers to each of these databases for related access. As shown, snapshot 711 is stored in master file 751, snapshot 712 is stored in master file 752, snapshot 713 is stored in master file 753, and snapshot 714 is stored in master file 754.

FIG. 8 is an illustration of multiple segments of the game play of a user of a video game, including an interceding jump by that user into a separate jump game play based on a snapshot captured during another game play of the video game by the same or another user, in accordance with one embodiment of the present disclosure. For example, the user playing a game with character 306 of which the currently rendered image 305 is displayed on window 300 as previously described in relation to FIGS. 3-6 may elect to jump into the game play of friend F1 (with character 308) at a jump point (JP) defined by snapshot image 360 e. Timeline 310 a and/or 310 b provides the user a preview of snapshot image 360 e. Further, node graph 530 gives context to the snapshot image within the video game, since the snapshot image 360 e can be associated with its corresponding location at snapshot node 572 (e.g., through highlighting, etc.), as previously described. Initiation by the user of the jump into the game play of friend F1 and character 308 is enabled based on the snapshot captured at snapshot node 572 during the original game play of friend F1. The initiation of the jump may be enabled through further selection of the snapshot image 360 e in timeline 310 a or 310 b, or through selection of node 572 in node graph 530. Support for initiation of the jump into the game play of the same or another user may be accomplished through any means or methods (e.g., jump selection window, etc.).

In one embodiment, a plurality of snapshots is captured in the jump game play. Further, a video recording of the jump game play may be captured and stored for later access. In that manner, any user may play the jump game play via any snapshot in the jump game play. In one embodiment, snapshot images of the jump game play are placed into a timeline, through which the jump game play may be instantiated, as previously described.

The interaction of the user with the video game may be described in relation to segments of game play 830 of the user. As shown, the game play 830 of the user includes a first segment 831 and a second segment 832. In particular, the first segment 831 of game play 830 of the user defines a current or initial interaction of the user with the video game. As such, the currently rendered image 305 of FIG. 3A may be associated with the first segment 831. For illustration, snapshot node graph 810 shows a portion of the node graph 530 previously described in relation to FIG. 5C. The route taken by a character 306 in the first segment 831 of the game play 830 of the user is shown by dotted line 811 and includes snapshot nodes 560, 561 and 562. Currently rendered image 305 is associated with snapshot node 562 and indicates the end of the first segment 831 for purposes of illustration and clarity, even though snapshot node graph 810 shows that character 306 has gone further to the right (e.g., progressed further) of snapshot node 562 to nodes 563 and 564 via one path 812, and to nodes 565 and 566 via a second path 813. This portion of the route (ending with snapshot node 562) taken by character 306 is also repeated in node graph 820, which illustrates the game play of the user using character 306 up to the end of the first segment 831.

At snapshot node 562, the user may choose to explore other points in the video game and elect to jump into the game play of friend F1 (e.g., further selection of snapshot image 360 e), as previously described. The game play of friend F1 is shown by the bolded, solid line 899 of snapshot node graph 810. At this point, the first segment 831 of the game play 830 of the user is paused, and the user jumps into the game play of friend F1 at a point corresponding to snapshot node 572. For illustration, the jump game play begins at a point where the character is closely engaged with a bear. In particular, the instance of the video game executing the game play 830 of the user is paused (e.g., end of first segment 831), and the instance of the video game executing the jump game play of friend F1 beginning at the jump point (snapshot node 572) is instantiated based on the corresponding snapshot captured at snapshot node 572. A representation of the jump to node 572 is illustrated by curved arrow 891. The jump game play is defined by jump segment 840.

In another embodiment, the game play 830 of the user is saved and terminated at the end of the first segment 831 before beginning the jump game play. In that manner, the user may return to the video game in the future and resume from a point corresponding to snapshot node 562 (e.g., end of first segment 831). That is, the user may effectively resume the paused game.

In one embodiment, the instance of the video game executing the game play 830 of the user is separate from the instance of the video game executing the jump game play through which the user interacts, wherein the jump game play is based on the original game play of friend F1. For illustration, snapshot node graph 850 shows the route taken by a character 308 in the jump segment 840 of the jump game play played by the user, wherein the character 308 in the jump game play was originally created and defined by the game play of friend F1. The route taken in the jump game play is illustrated through bolded and dotted line 896.

The route taken by the character 308 in the jump game play as illustrated in node graph 850 begins at snapshot node 572 and continues to nodes 851, 852, and end node 859 consecutively. End node 859 indicates the termination of the instance of the video game executing the jump game play. It is important to note that the route taken by the character 308 in the jump game play (including nodes 572, 851, 852, and 859) as shown by dotted line 896 is different than the route 897 (including nodes 572, 573, and 574) taken by the character 308 in the game play of friend F1 shown in node graph 810. That is, the jump game play as executed by the user is different than the previously stored game play of friend F1 because the user is providing new input commands to direct the jump game play. For example, in the jump game play an unsuccessful encounter with the bear may occur because the user may be quickly previewing the game at this point to decide whether or not to play this part of the video game in his or her own game play 830. On the other hand, the game play of the find F1 may show a successful encounter with the bear.

In one embodiment, during the jump game play, snapshots may be captured at each of the nodes illustrated in jump segment 840 (e.g., nodes 572, 851, 852, and 859). The jump game play and its associated snapshots may be stored for later access. Further, a video recording of the jump game play may be recorded and stored. For example, the user may wish to review and instantiate jump game plays created by the user and associated with the video game. In other embodiments, the user may wish to review and instantiate jump game plays associated with other video games, wherein the jump game plays were created by the user or other users. Moreover, any user can experience the jump game play of the user via a captured snapshot, and through a secondary jump game play that is newly instantiated. In particular, a selected snapshot captured during the jump game play can be used to instantiate an instance of a gaming application to execute a secondary jump game play based on the selected snapshot captured during the primary jump game play. As such, any user is able to experience any previous jump game play created by the same user, or may be able to experience stored jump game plays of other players.

After execution of the jump game play, the game play 830 of the user may be resumed. The user has now previewed the game play of the friend F1, and may wish to have his or her own character 306 reach snapshot node 572 that is associated with the jump point. In that manner, the game play 830 of the user may include a route that is directed towards the jump point so that the character in the game play of the user will have the same bear encounter.

Snapshot node graph 820 shows the route taken by a character in the game play 830 of the user that is now resumed. The resumption of game play 830 is defined by second segment 832, wherein the resumed game play is defined by bolded and dotted line 809. As such, the entirety of the game play 830 by user is illustrated by the first segment 8310 (dotted line 811) and the second segment 832 (bold and dotted line 809). In one embodiment, the second segment 832 of game play 830 continues the instance of the video game that is paused. In another embodiment, the second segment 832 of game play 830 is executed on a new instance of the video game beginning at the point of the video game associated with snapshot 562, because the first segment 831 was terminated. The second segment 832 begins at snapshot node 562, and continues to snapshot nodes 821, 822, 823, 824, and 829 consecutively.

In node graph 820, snapshot node 823 roughly corresponds to the snapshot node 572 associated with the jump point. For example, the user would like to encounter the bear in his or her own game play 830. In particular, navigation to snapshot node 572 in the game play of the user is possible by the user via snapshot node graph 530 and/or universal node graph 550. In particular, the user is able to discover the possible paths available between snapshot node 562 and snapshot node 572 encountered by other users (e.g., friend F1) by reviewing the snapshot node graph 530. Additionally, the user is able to discover the general logical paths available between snapshot node 562 and snapshot node 572 by reviewing the universal node graph 550. In that manner, the user is able to navigate to a snapshot node 823 (e.g., via nodes 821 and 822) and encounter the bear. It is important to note that nodes 821 and 822 roughly align with snapshot nodes 565 and 570, originally captured during the game play of friend F1, but may not be identical.

Snapshot nodes 823, 824, and 829, etc. show the route taken in the game play 830 of the user, in the second segment 832, wherein the character 306 is now encountering and engaging with the bear. The route taken after the initial encounter with the bear at snapshot node 823 (including nodes 824, 829, etc.) may not be identical with the route in the jump game (e.g., nodes 572, 851, 852, and 859), nor may it be identical with the route in the game play of friend F1 (e.g., nodes 572, 573, and 574). This is because the game play 830 of the user has its own unique input commands that drive the video game.

With the detailed description of the various modules of the gaming server and client device communicating over a network, a method for navigating through a gaming world of a video game executing over a gaming network is now described in relation to flow diagram 900 of FIG. 9, in accordance with one embodiment of the present disclosure. Flow diagram 900 illustrates the process and data flow of operations involved at the game server side for purposes of generating information that is displayed over a network at a client device.

The method begins at operation 910, and includes capturing a plurality of snapshots generated from a plurality of instances of a video game executed in association with a plurality of users. In particular, the instances of the video game are being executed by one or more game processors 210 of one or more game servers 205 of FIG. 1. As each instance of the video game is being executed, one or more snapshots are captured, wherein a snapshot enables execution of an instance of the video game beginning from a point in the video game corresponding to that snapshot, as previously described.

In particular, the snapshot includes a snapshot image that comprises a rendered image generating by the instance of the video game that is executed in association with a game play of a corresponding user. The rendered image shows a scene of the video game corresponding to a point in the video game, wherein the point shows the progression in the game play of the user through the video game.

In addition, the snapshot also includes game state data that enables the generation of an environment corresponding to point in the video game. That is, based on the snapshot the corresponding scene and environment are generated, wherein the character is instructed to interact with the environment through the game play of the user.

Further, the snapshot includes random seed data providing additional features for the scene and environment, as previously described. For example, a cloud configuration and movement of one or more generic characters may be uniquely generated for inclusion into the scene and environment that is associated with the game play of the user. As such, the cloud configuration and movement of one or more generic characters may be different for each instance of the video game.

Also, the snapshot includes user saved data that enables generation of a character for the game play of the corresponding user. The character has a first state corresponding to point in video game at which the snapshot was captured. For example, the first state defines the look and type of the character, the clothing worn by the character, the level achieved for the character, the weaponry available to the character, the life status for the character at that point, etc.

At operation 920, the method includes generating for display a first timeline of a first user playing the video game. The first timeline includes snapshot images of at least one user (the first user and/or other users) progressing through the video game. The snapshot images in the timeline are displayed in relation to a currently rendered image of a first instance of the video game executing in association with the first user. Each snapshot image can be cross-referenced to a corresponding snapshot. The currently rendered image is associated with a current point in the progression of the video game by the first user.

At operation 930, the method includes generating for display in the first timeline a plurality of first thumbnails including a plurality of first snapshot images associated with the first user. That is, the first thumbnails show the progress through the video game of the first user. In particular, the plurality of first snapshots includes at least one rendered image showing past progress of the first user in comparison to the currently rendered image.

At operation 940, the method includes generating for display in the first timeline a plurality of second thumbnails including a plurality of second snapshot images associated with a second user. That is, the second thumbnails show the progress through the video game of the second user. In particular, the plurality of second snapshot images includes at least one rendered image showing progress of the future progress of the second user at a point in the video game after the currently rendered image.

In other implementations the plurality of second snapshot images shows past and/or current progress of the second user. For example, the second snapshots includes at least one rendered image showing progress of the second user at a point in the video game before the currently rendered image generated for display at a client device of the first user.

In still other embodiments, additional timelines may be generated for display at the client device. For example, a second timeline of a third user is generated for display. The second timeline includes a plurality of third snapshot images of the third user. The second timeline includes a plurality of rendered images showing progress of the third user during game play of the video game at a plurality of points in the video game before and after the currently rendered image associated with the game play of the first user.

As previously described, a selected snapshot image enables the jump executing engine 216 of game processor 210 to access the snapshot corresponding to snapshot image, instantiate another instance of the video game based on the snapshot, and execute the video game beginning at a point (now identified as a jump point) in the video game corresponding to the snapshot. For example, the game processor 210 receives selection by the first user of a selected snapshot image from the plurality of second snapshots in the first timeline, wherein the selected snapshot image is associated with game play of the second user. Further, the game processor is configured to jump execution of a first instance of the video game executed in association with game play of the first user to a jump point in the video game associated with the selected snapshot image. In one implementation, the first instance of the video game is paused and/or terminated, and another instance of the video game, the jump game, is instantiated based on the snapshot of the selected snapshot image.

In that manner, the first user is able to jump into the game play of the second user. For instance, the first user is able to instruct the character used in the game play of the second user in the jump game. The corresponding snapshot of the selected snapshot image includes second user saved data enabling generation of the character used in the game play of the second user, and also used for a jump game play of the first user in the jump game. The second user saved data and the second character originate from the game play of the second user. As such, the first user creates a jump game play during execution of the jump game.

After the first user is finished with the jump game, the first instance of the video game may be resumed. That is, the second instance of the video game executing the jump game is terminated, and the first instance of the video game associated with the game play of the first user is resumed. In that manner, the first user may resume his or her own game play of the video game.

The first user may also select a snapshot image in the prior game play of the first user. For example, the game processor may be configured to receive selection of a selected snapshot image in the plurality of first snapshot images associated with the prior game play. Execution of the first instance of the video game is jumped to a jump point in the video game associated with the selected snapshot image. In one implementation jumping is enabled through another instance of the video game based on the snapshot corresponding to the selected snapshot image. In another implementation, jumping is enabled through the first instance of the video game.

In addition, a node graph may be generated for display at the client device. The node graph includes a plurality of snapshot nodes corresponding to snapshot images displayed in the timeline, as previously described. The plurality of snapshot nodes defines a plurality of paths, wherein the paths and nodes are associated with game plays of the first user and the second user. Each node in the node graph is associated with a corresponding snapshot.

Further, the node graph may allow for jumping by the first user into the game play of the same or another user. For example, the game processor is configured to receive selection of a selected snapshot node in the node graph. The snapshot node is associated with a corresponding snapshot. A selected snapshot image corresponding to the selected snapshot node may optionally be generated for display at the client device. In particular, selection of the selected snapshot node and/or corresponding snapshot image enables jumping of the execution of the first instance of the video game executed in association with game play of the first user to a jump point in the video game associated with the selected node.

While specific embodiments have been provided to demonstrate the generation and capture of snapshots of points in game plays of a video game for of multiple users that are used for previewing and/or jumping to a previously executed game play of the same or another user, these are described by way of example and not by way of limitation. Those skilled in the art having read the present disclosure will realize additional embodiments falling within the spirit and scope of the present disclosure.

It should be noted, that access services, such as providing access to games of the current embodiments, delivered over a wide geographical area often use cloud computing. Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users do not need to be an expert in the technology infrastructure in the “cloud” that supports them. Cloud computing can be divided into different services, such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Cloud computing services often provide common applications, such as video games, online that are accessed from a web browser, while the software and data are stored on the servers in the cloud. The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams and is an abstraction for the complex infrastructure it conceals.

A Game Processing Server (GPS) (or simply a “game server”) is used by game clients to play single and multiplayer video games. Most video games played over the Internet operate via a connection to the game server. Typically, games use a dedicated server application that collects data from players and distributes it to other players. This is more efficient and effective than a peer-to-peer arrangement, but it requires a separate server to host the server application. In another embodiment, the GPS establishes communication between the players and their respective game-playing devices to exchange information without relying on the centralized GPS.

Dedicated GPSs are servers which run independently of the client. Such servers are usually run on dedicated hardware located in data centers, providing more bandwidth and dedicated processing power. Dedicated servers are the preferred method of hosting game servers for most PC-based multiplayer games. Massively multiplayer online games run on dedicated servers usually hosted by a software company that owns the game title, allowing them to control and update content.

Users access the remote services with client devices, which include at least a CPU, a display and I/O. The client device can be a PC, a mobile phone, a netbook, a PDA, etc. In one embodiment, the network executing on the game server recognizes the type of device used by the client and adjusts the communication method employed. In other cases, client devices use a standard communications method, such as html, to access the application on the game server over the internet.

Embodiments of the present disclosure may be practiced with various computer system configurations including hand-held devices, microprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers and the like. The disclosure can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a wire-based or wireless network.

It should be appreciated that a given video game may be developed for a specific platform and a specific associated controller device. However, when such a game is made available via a game cloud system as presented herein, the user may be accessing the video game with a different controller device. For example, a game might have been developed for a game console and its associated controller, whereas the user might be accessing a cloud-based version of the game from a personal computer utilizing a keyboard and mouse. In such a scenario, the input parameter configuration can define a mapping from inputs which can be generated by the user's available controller device (in this case, a keyboard and mouse) to inputs which are acceptable for the execution of the video game.

In another example, a user may access the cloud gaming system via a tablet computing device, a touchscreen smartphone, or other touchscreen driven device. In this case, the client device and the controller device are integrated together in the same device, with inputs being provided by way of detected touchscreen inputs/gestures. For such a device, the input parameter configuration may define particular touchscreen inputs corresponding to game inputs for the video game. For example, buttons, a directional pad, or other types of input elements might be displayed or overlaid during running of the video game to indicate locations on the touchscreen that the user can touch to generate a game input. Gestures such as swipes in particular directions or specific touch motions may also be detected as game inputs. In one embodiment, a tutorial can be provided to the user indicating how to provide input via the touchscreen for gameplay, e.g. prior to beginning gameplay of the video game, so as to acclimate the user to the operation of the controls on the touchscreen.

In some embodiments, the client device serves as the connection point for a controller device. That is, the controller device communicates via a wireless or wired connection with the client device to transmit inputs from the controller device to the client device. The client device may in turn process these inputs and then transmit input data to the cloud game server via a network (e.g. accessed via a local networking device such as a router). However, in other embodiments, the controller can itself be a networked device, with the ability to communicate inputs directly via the network to the cloud game server, without being required to communicate such inputs through the client device first. For example, the controller might connect to a local networking device (such as the aforementioned router) to send to and receive data from the cloud game server. Thus, while the client device may still be required to receive video output from the cloud-based video game and render it on a local display, input latency can be reduced by allowing the controller to send inputs directly over the network to the cloud game server, bypassing the client device.

In one embodiment, a networked controller and client device can be configured to send certain types of inputs directly from the controller to the cloud game server, and other types of inputs via the client device. For example, inputs whose detection does not depend on any additional hardware or processing apart from the controller itself can be sent directly from the controller to the cloud game server via the network, bypassing the client device. Such inputs may include button inputs, joystick inputs, embedded motion detection inputs (e.g. accelerometer, magnetometer, gyroscope), etc. However, inputs that utilize additional hardware or require processing by the client device can be sent by the client device to the cloud game server. These might include captured video or audio from the game environment that may be processed by the client device before sending to the cloud game server. Additionally, inputs from motion detection hardware of the controller might be processed by the client device in conjunction with captured video to detect the position and motion of the controller, which would subsequently be communicated by the client device to the cloud game server. It should be appreciated that the controller device in accordance with various embodiments may also receive data (e.g. feedback data) from the client device or directly from the cloud gaming server.

It should be understood that the embodiments described herein may be executed on any type of client device. In some embodiments, the client device is a head mounted display (HMD).

FIG. 10, a diagram illustrating components of a head-mounted display 1050 is shown, in accordance with an embodiment of the disclosure. The head-mounted display 1050 includes a processor 1000 for executing program instructions. A memory 1002 is provided for storage purposes, and may include both volatile and non-volatile memory. A display 1004 is included which provides a visual interface that a user may view. A battery 1006 is provided as a power source for the head-mounted display 1050. A motion detection module 1008 may include any of various kinds of motion sensitive hardware, such as a magnetometer 1010, an accelerometer 1012, and a gyroscope 1014.

An accelerometer is a device for measuring acceleration and gravity induced reaction forces. Single and multiple axis models are available to detect magnitude and direction of the acceleration in different directions. The accelerometer is used to sense inclination, vibration, and shock. In one embodiment, three accelerometers 1012 are used to provide the direction of gravity, which gives an absolute reference for two angles (world-space pitch and world-space roll).

A magnetometer measures the strength and direction of the magnetic field in the vicinity of the head-mounted display. In one embodiment, three magnetometers 1010 are used within the head-mounted display, ensuring an absolute reference for the world-space yaw angle. In one embodiment, the magnetometer is designed to span the earth magnetic field, which is ±80 microtesla. Magnetometers are affected by metal, and provide a yaw measurement that is monotonic with actual yaw. The magnetic field may be warped due to metal in the environment, which causes a warp in the yaw measurement. If necessary, this warp can be calibrated using information from other sensors such as the gyroscope or the camera. In one embodiment, accelerometer 1012 is used together with magnetometer 1010 to obtain the inclination and azimuth of the head-mounted display 1050.

A gyroscope is a device for measuring or maintaining orientation, based on the principles of angular momentum. In one embodiment, three gyroscopes 1014 provide information about movement across the respective axis (x, y and z) based on inertial sensing. The gyroscopes help in detecting fast rotations. However, the gyroscopes can drift overtime without the existence of an absolute reference. This requires resetting the gyroscopes periodically, which can be done using other available information, such as positional/orientation determination based on visual tracking of an object, accelerometer, magnetometer, etc.

A camera 1016 is provided for capturing images and image streams of a real environment. More than one camera may be included in the head-mounted display 1050, including a camera that is rear-facing (directed away from a user when the user is viewing the display of the head-mounted display 1050), and a camera that is front-facing (directed towards the user when the user is viewing the display of the head-mounted display 1050). Additionally, a depth camera 1018 may be included in the head-mounted display 1050 for sensing depth information of objects in a real environment.

In one embodiment, a camera integrated on a front face of the HMD may be used to provide warnings regarding safety. For example, if the user is approaching a wall or object, the user may be warned. In one embodiment, the use may be provided with an outline view of physical objects in the room, to warn the user of their presence. The outline may, for example, be an overlay in the virtual environment. In some embodiments, the HMD user may be provided with a view to a reference marker, that is overlaid in, for example, the floor. For instance, the marker may provide the user a reference of where the center of the room is, which in which the user is playing the game. This may provide, for example, visual information to the user of where the user should move to avoid hitting a wall or other object in the room. Tactile warnings can also be provided to the user, and/or audio warnings, to provide more safety for when the user wears and plays games or navigates content with an HMD.

The head-mounted display 1050 includes speakers 1020 for providing audio output. Also, a microphone 1022 may be included for capturing audio from the real environment, including sounds from the ambient environment, speech made by the user, etc. The head-mounted display 1050 includes tactile feedback module 1024 for providing tactile feedback to the user. In one embodiment, the tactile feedback module 1024 is capable of causing movement and/or vibration of the head-mounted display 1050 so as to provide tactile feedback to the user.

LEDs 1026 are provided as visual indicators of statuses of the head-mounted display 1050. For example, an LED may indicate battery level, power on, etc. A card reader 1028 is provided to enable the head-mounted display 1050 to read and write information to and from a memory card. A USB interface 1030 is included as one example of an interface for enabling connection of peripheral devices, or connection to other devices, such as other portable devices, computers, etc. In various embodiments of the head-mounted display 1050, any of various kinds of interfaces may be included to enable greater connectivity of the head-mounted display 1050.

A WiFi module 1032 is included for enabling connection to the Internet via wireless networking technologies. Also, the head-mounted display 1050 includes a Bluetooth module 1034 for enabling wireless connection to other devices. A communications link 1036 may also be included for connection to other devices. In one embodiment, the communications link 1036 utilizes infrared transmission for wireless communication. In other embodiments, the communications link 1036 may utilize any of various wireless or wired transmission protocols for communication with other devices.

Input buttons/sensors 1038 are included to provide an input interface for the user. Any of various kinds of input interfaces may be included, such as buttons, touchpad, joystick, trackball, etc. An ultra-sonic communication module 1040 may be included in head-mounted display 1050 for facilitating communication with other devices via ultra-sonic technologies.

Bio-sensors 1042 are included to enable detection of physiological data from a user. In one embodiment, the bio-sensors 1042 include one or more dry electrodes for detecting bio-electric signals of the user through the user's skin.

The foregoing components of head-mounted display 1050 have been described as merely exemplary components that may be included in head-mounted display 1050. In various embodiments of the disclosure, the head-mounted display 1050 may or may not include some of the various aforementioned components. Embodiments of the head-mounted display 1050 may additionally include other components not presently described, but known in the art, for purposes of facilitating aspects of the present disclosure as herein described.

It will be appreciated by those skilled in the art that in various embodiments of the disclosure, the aforementioned handheld device may be utilized in conjunction with an interactive application displayed on a display to provide various interactive functions. The exemplary embodiments described herein are provided by way of example only, and not by way of limitation.

FIG. 11 is a block diagram of a Game System 1100, according to various embodiments of the disclosure. Game System 1100 is configured to provide a video stream to one or more Clients 1110 via a Network 1115. Game System 1100 typically includes a Video Server System 1120 and an optional game server 1125. Video Server System 1120 is configured to provide the video stream to the one or more Clients 1110 with a minimal quality of service. For example, Video Server System 1120 may receive a game command that changes the state of or a point of view within a video game, and provide Clients 1110 with an updated video stream reflecting this change in state with minimal lag time. The Video Server System 1120 may be configured to provide the video stream in a wide variety of alternative video formats, including formats yet to be defined. Further, the video stream may include video frames configured for presentation to a user at a wide variety of frame rates. Typical frame rates are 30 frames per second, 60 frames per second, and 1120 frames per second. Although higher or lower frame rates are included in alternative embodiments of the disclosure.
